Question

我需要将动态添加的DOM元素（可拖动的DIV）保存到文件中，并在以后加载它们。实现这一目标的最简洁方法是什么？

Answer 1

您可以保存mySql或Mongodb

var mysql      = require('mysql');
var connection = mysql.createConnection({
    host     : 'locahost',
    user     : 'foo',
    password : 'bar',
    database : 'test'
});

// the callback inside connect is called when the connection is good
connection.connect(function(err){
    var sql = "select 'Joe' as name from dual";

    connection.query(sql, function(err, rows, fields) {
        if (err) return console.log(err);
        //  you need to end your connection inside here.
        connection.end();
        console.log(rows[0].name);
    });
});
